Abstract
An ink reduction rate is set in accordance with the type of image and the type of recording medium. For example, when a photograph is to be printed on a glossy paper with low resolution, the ink reduction rate is set to 10%. When a photograph is to be printed on a plain paper with low resolution, the ink reduction rate is set to 25%. When a document is to be printed with low resolution, the ink reduction rate is set to 50%, irrespective of the type of recording paper.
Claims16
A non-transitory computer readable storage medium storing a data processing program for controlling a computer to perform steps comprising:
- inputting data;
- detecting a type of the inputted data;
- determining an ink reduction rate based on the type of the inputted data by referencing a table indicating correspondences between a plurality of ink reduction rates and a plurality of types of data,
- wherein each ink reduction rate of the plurality of ink reduction rates indicates a ratio of a difference between a first ink consumption amount and a second ink consumption amount to the first ink consumption amount,
- wherein the first ink consumption amount indicates an ink amount to be consumed when printing is executed without reducing ink,
- wherein the second ink consumption amount indicates an ink amount to be consumed when printing is executed with reducing ink, and
- wherein the plurality of ink reduction rates comprises a first ink reduction rate and a second ink reduction rate that is different from the first ink reduction rate;
- and
- correcting the inputted data based on the determined ink reduction rate,
- such that an ink amount to be consumed when printing the inputted data is reduced by using the first ink reduction rate when the inputted data is classified into first type image data, and
- such that the ink amount to be consumed when printing the inputted data is reduced by using the second ink reduction rate when the inputted data is classified into second type image data that is different from the first type image data.
A data processing device comprising:
- an inputting unit that inputs data;
- a detecting unit that detects a type of the inputted data;
- a determining unit that determines an ink reduction rate based on the type of the inputted data by referencing a table indicating correspondences between a plurality of ink reduction rates and a plurality of types of data,
- wherein each ink reduction rate of the plurality of ink reduction rates indicates a ratio of a difference between a first ink consumption amount and a second ink consumption amount to the first ink consumption amount,
- wherein the first ink consumption amount indicates an ink amount to be consumed when printing is executed without reducing ink,
- wherein the second ink consumption amount indicates an ink amount to be consumed when printing is executed with reducing ink, and
- wherein the plurality of ink reduction rates comprises a first ink reduction rate and a second ink reduction rate that is different from the first ink reduction rate;
- and
- a correcting unit that corrects the inputted data based on the determined ink reduction rate,
- such that an ink amount to be consumed when printing the inputted data is reduced by using the first ink reduction rate when the inputted data is classified into first type image data, and
- such that the ink amount to be consumed when printing the inputted data is reduced by using the second ink reduction rate when the inputted data is classified into second type image data that is different from the first type image data.
